What is the Dallas Horseshoe Project?


The Dallas Horseshoe Project is a $798 million design-build roadway construction project by the Texas Department of Transportation (TxDOT) to improve traffic flow through the heart of downtown Dallas. Aptly dubbed the “Horseshoe project” due to its U shape, the project is dedicated to “Fixin’ the Mix”. Construction improvements include the expansion, repaving and addition of several new bridges and roadways along interstates 30 and 35E; and the construction of a new signature bridge, the Margaret McDermott Bridge, over I-30.


The project started in April 2013 and is scheduled to be complete as early as 2017. Once completed, drivers should experience improved safety, increased capacity and improved mobility through the downtown Dallas Mixmaster and the central business district.
